This is a free 3D laser cut pendant lamp built from 14 flat parts, drawn for 3 mm sheet material. Assembled, the shade stands 346.4 mm tall with a diameter of 175.7 mm, giving it the scale of a physical pendant shade. The files are supplied for laser cutting workflows in DXF, SVG, CDR, DWG, and PDF.
Laser Cut Pendant Lamp Design and Light Pattern
I designed this lamp around the light it casts, not only around how the panels look flat on the sheet. The body is a cylinder of twelve vertical side panels, eight wider and four narrower, that close into a continuous ring. Each panel carries a flowing wave opening running down its length. Those waves are the point: with the bulb inside the cylinder, the light has to pass through the curved wall, and the wave openings shape how it spreads into the room. I drew them as smooth, continuous curves so the cut edge follows the wave cleanly and the light pattern stays soft rather than broken up.
The top is a circular plate cut with a sun-like radial pattern around a center hole. I gave it that pattern for a reason beyond holding the lamp together. The radial slots let light escape upward, so the fixture throws a second, softer glow onto the ceiling while the side waves light the space around it. Building the lamp around these two effects, the side waves outward and the sun pattern upward, was the real design work here. Drawing those patterns so they read well to the eye and still cut and assemble cleanly took far longer than laying out the parts themselves.
The fourteenth piece is a lower inner support ring. It sits inside the lower body and keeps the panels aligned and evenly spaced around the base, so the cylinder holds its round shape down its full height. It is an internal aligning ring, not a closed bottom, so the underside of the shade stays open and the bulb stays reachable. Each side panel also keeps a continuous solid border around its wave openings, so no panel is cut so far that it loses its own frame. Between the radial top plate squaring the upper edge and the support ring bracing the base, the body is designed to stay supported at both ends.
The parts are drawn to fit together tightly. I did not add a separate fit tolerance into the slots, because the laser kerf removes a thin band of material during cutting, and that helps create the seating clearance for the joints. This is also why your material matters, which leads into the cutting notes below.
Cutting Notes for 3 mm Sheet Material
Real 3 mm sheet drifts with humidity, temperature, manufacturer, and sheet quality, so the slot fit depends on the stock you actually run. Suitable 3 mm sheet materials can include wood sheet, plywood, MDF, or acrylic, depending on the machine, material quality, and desired finish.
A few practical notes before cutting:
- Drawn for 3 mm sheet material
- Suitable materials can include wood sheet, plywood, MDF, or acrylic
- Slots are drawn for a tight fit, with laser kerf helping the joints seat
- Measure the actual sheet thickness with calipers before cutting
- Adjust scale or slot fit if the sheet is not close to 3 mm
- Use suitable LED lighting hardware; bulb, socket, cord, and canopy are not included
